The title compound Cu(sahm)_2·4H_2O(sahm=4-Salicysilidene-amine-3,5-dihydrox-ymethyl-1,2,4-triazole) was synthesized by reaction of sahm with copper chloride(CuCl_2) and obtained in the form of single crystals.C_(22)H_(30)CuN_8O_(10),M_r=629. 5. The crystal structure has been determined.Crystal data : monoclinic,space group P2_1/c,with a=8.3189(8) A ,b= 9.827(1) A,c=16.126(2)A,β=102.585(9)°,V=1286.6 A￣3, Z=2,D_x=1.48 g/cm￣3,μ=0.907 mm(-1),F(000)=598,R=0.042.R_w=0.057.The structure analysis shows that copper ion was coordinated by two phenoxy atoms and two nitrogen atoms of the azomethene to form a regular rhombic plane.
